Description
The BGA715L7 is a front-end low noise amplifier for Global Positioning System (GPS) applications. The LNA provides 20 dB gain, 0.7 dB noise figure and high linearity performance in the application configuration described in Chapter 4. Current consumption is as low as 3.3 mA. The BGA715L7 is based upon Infineon Technologies` B7HFM Silicon Germanium technology. It operates over a 1.5 V to 3.3 V supply range. If an ultra low noise figure of 0.6 dB is required, please refer to Infineon BGA715L7 Application Note AN161.
